[PATCH AUTOSEL 5.18 03/53] spi: spi-mem: Fix spi_mem_poll_status()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Patrice Chotard <patrice.chotard@xxxxxxxxxxx>

[ Upstream commit 2283679f4c468df367830b7eb8f22d48a6940e19 ]

In spi_mem_exec_op(), in case cs_gpiod descriptor is set, exec_op()
callback can't be used.
The same must be applied in spi_mem_poll_status(), poll_status()
callback can't be used, we must use the legacy path using
read_poll_timeout().

Tested on STM32mp257c-ev1 specific evaluation board on which a
spi-nand was mounted instead of a spi-nor.
